Can you please fix the blank screen issues?
Everytime I open the app on Android I have to log out and sign back in for it to load anything.

Sorry for posting this on here but I just stumbled upon this post/website and happen to have an issue with the app that didn't seem to be getting fix from what I can tell.

I love the app, it's just this issue makes me not want to use it anymore.

Hey zXenn_VS, thanks for reaching out. I always love seeing our users getting in touch with us about ways we can improve the app. We take those concerns seriously and always investigate them so thank you.

That said - we actually have an update coming out next week which addresses issues users were experiencing where they needed to sign out and in. Hang tight and keep an eye out for it. If you still experience the same issue after the update comes out then please DM me on Twitter and we can dig a little deeper into the issue.

Hey Tim, strangely I decided to see if the update was available yet and it was and within 30 secs of pressing update got notified by Twitter that you followed me.

I'll check out the update soon and get back to you. Thanks for keeping me upto date.

My squad won the weekly tournament that had just ended last night. We were placed into a new tournament with two squads already up to 390 and 208 wins at only 11 hours in. Only problem is, these wins are coming from only one person in each squad. When I look at their recent activity or matches, I noticed they lose a lot more than they are getting wins and they have only been playing for 8 hours. When we won last week, we had to add active friends to our squad and play for a whole day with almost every game being a win but that was with the whole squad, this is one dude getting 390 points in 11 hours!! How are we supposed to even compete with that???

Update: Misread the tournament requirements for this week! Didn't know it changed from "wins" to "tdm kills"

Hi Lauren. Thanks for reaching out. I've passed your feedback along. Please note that this weeks challenge isn't "wins" it's actually "kills".

I found this out after I posted! I apologise! Thanks for the reply though! These weekly tournaments are honestly the only thing I really play Modern Warfare for

It's okay. I'm happy to hear you enjoy the weekly tournament because I was primarily the one who built it. It's always nice to see it being enjoyed. Please feel free to reach out in the future if you see any issues. :)

Are there any plans for a load out editor on the app? I think it would be really useful and is honestly the only thing I think the app could use to make it better.

Hi Sierra. Thanks for reaching out.

We currently support a loadout editor in the app for BlackOps 4. The loadout editor for Modern Warfare is actively being worked on. Please stay tuned. :)

Hey Joni. If you could let me know your username in the app that might be a good starting point for me to investigate further. Thanks

We have an update coming out later today (update 2.3.0). When it's out can you please download it from your app store and let me know if you're still experiencing the crash?

I downloaded the new update 2.3.0 and it still keeps crashing. I tried to redownload the whole app but it didn't work. My phone is a few years old and has Android 6.0 so that May affect the app from working but I've heard other people with newer phones and android versions having the same problem.

Thanks Joni. I'll keep investigating. In the meantime, could you send a video of how you trigger the crash as a DM to me on Twitter please?

Curiously what was the reason moving from React Native Navigation to React Navigation?

One time in a bar Nader Dabit told me he liked it better. Just kidding. Though that did happen.

RNN wasn't a good fit for us. A lot of apps that have a significant enough amount of native modules tend to use it. But we basically don't have any native modules. Nor do we care about features RNN offers. We felt RN was simpler, had a more reliable buy-in (meaning better maintained), & fit our upcoming use cases for deeplinks better. We liked how it worked with react-native-screens too. It has cool stuff like lazy loading too which was easy for us to take advantage of.

Thanks for response! We've lived with RNN for a while now and found it quite difficult to work with, however have enjoyed the native feel and performance.

I'll have a look into react-native-screens with react-navigation, so thanks for that tip.

Personally I can't tell any difference in terms of performance. If it's there it feels negligible enough that the pros of RN still count much more heavily in its favor. Though to be fair we did a lot of performance improvements alongside moving away from RNN so I don't have a proper comparison - I just know our performance now with RN doesn't appear to be any sort of problem.

If your application uses a lot of native modules your experience may indeed be different. That is not an area I am particularly knowledgeable about.
